I in the market for another motorhome. I had the F53 and could never got it to track straight. Yes, I did a bunch of upgrades and changes and it got better but was never right. I’m considering going...

In years past I had two or three of GM's P30 chassis' under my motorhomes. They were all had to keep in one lane especially when there was a wind blowing. The problem is the factory bellcranks. The introduce so much play and slop into the steering it's criminal. I never coughed up the cash for the SuperSteer tapered roller bearing bellcranks that chassis should have come with as standard but I did try buying a new housing and pin from GM. It came with so much slop (about and 1/8 of an inch) I refused to accept it - it was special order and made the parts guy made as hell.
The GM P30 has independent front suspension with coil springs while the F53 has a solid front axle using kingpins like most heavy duty vehicles. My last two motorhomes have been on the F53 and the only trouble I've had is trying to get a smooth ride from tires. I spent a lot of money trying to get them balanced properly but some of that may be the brand of tires I'm dealing with. Next time I buy tires, the dealer better expect to hear all kinds of flack if they can't make me happy. I don't blame my out of balance problems on the chassis.
I wouldn't want another motorhome on the P30 chassis. The GM/Workhorse "W" series chassis has a solid front axle that I would much prefer over the P series.
